Guss-nomme Application led July 11,

To 'all whom it may cmwem: l

Be it known that I, AUGUST KAnow, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Glass-Forming Machines, of which the following is a specification.

My invention relates to a machine for forming hollow glass articles, such, for i example, as incandescent electric light bulbs; andthe invention has forits object to provide new and improved apparatus for performing automatically certain operations in the manufacture of articles of the sort ll which heretofore have ordinarily been carried out by hand labor.

The invention has for one of its principal objects to provide a glass gathering dev ice of novel and improved construction which l can be osc'illatedso as to bring the body of glass held thereon into different positions which it must take while being operated upon to produce the article to be 'manufactured; andin which the gathering member, l that is, the blow pipe or other element which `fathers or supports the bod of glass opcrated u on, is axially rotata le so that the blank o lass may be revolved on its axis either during the oscillating movements'of i 30 the gathering device, or at other times, as may be required by the conditions under which the article is manufactured.

A further object of the invention is to y provide suitable mechanisms for automatl 35 cally effecting the above mentioned oscillatingand revoluble movements of the parts of the gathering device.

A further object ofthe invention is to provide means whereby the mechanism for lo axially revolvinr the blank may be cut out of action when this is necessary or desirable.

A further object of the invention is to provide an oscillating and revoluble gathering device through which air under pressure ,3' ma;v be directed so as to act upon the blank. The invention has for further objects the certain new and improved. constructions, arrangements and devices in glass forming! apparatus which -will be hereinafter deu scribed and claimed.

The invention is illustrated in a referred embodiment in the accompanying rawings,

whereinme. semina. 571,439. l

Like characters of reference indicate like parts in the several figures of the drawings.' I

The invention is embodied in a machine consisting, broadly speaking, of a central column which is stationary, around which revolves a frame which carries the operative devices. of the machine,l which latter are actuated to perform in successiontheseveral e operations which the'inacliine is desi' ed to carry out through vthe instrumentalnity of stationary cams and a rack located on the l column.

Referring to the drawings, designates the stationary column to which are secured the cam carrying rings 22 and 23. To the upper side of the former is bolted the cam member 24 on which is formed the cani or cam-way-25 in which operates the cam roller or follower 26. The cam member 24 is referably formed with the slots 27 for justment on the ring 22. .On the under side of i.

ring 22 is bolted a ring 28 to whichis bolted a circular rack 29 which isfmeshed by a pinion 30. These two' mechanisms, the cam mechanism and the rack and pinion mechanism accomplish most of j th'e operations I which the machine performs. Certain other operations are performed by other cams 'l which will be hereinafter described.

The manipulation Aofthe 'glass isv perf n formed 'by means ofa rathering' device piv otally and revolubly mounted on the frame .,1

which revolves about the pillar 20. On this frame the `lowerA member or platform of which is designated 31 (Fig. 11) are two standards 32, to which are bolted the brackets 33 of a frame consisting of the vertical web 34 and the preferable angular projectinv su porting members 35, 35a. 0n the entds o the. latter are bearings 36, 361 which rotatably support the gathering device or blow pipe.

rlthe gathering device or blow pipe is preferably constructed as follows: 37 is a hollow casing formed with bosses 38 and 39. Boss 38 receives the end of a shaft 40, which turns in bearing 36, the boss being secured to the shaft by the set-screw 41 (Fig. 10). Boss 39 is su ported, but revolubly on the end of a sha 42in bearing 36D. Within casing 37 is a spindle 43, one end of which is threaded for the nut 44 which holds a set of balls 45 against their race-way 46 secured within the casing 37; these parts beine enclosed by a cap piece 47. The spindle 43 is also formed with a shoulder 48, between which and the race-way 49 at the other end of casing 87 are a set of balls 59; these parts being enclosed by the cap piece 51 provided preferably with the packing 52. The spindle43 is formed with a bore 53 communicating b a branch 54 with the space within the casing 37. The shaft 40 is formed with a bore 55 which registers with a bore 56 in a cap piece 57 which closes the end of bearing 36. Into the cap piece 57 is tapped a pipe 58 which is connected with a source of supply of compressed air (not shown). A packinor washer 59 is interposed between the en of shaft 40 and cap piece 57. The bore 53 of spindle 43 is enlarged at 60 and receives the end of the glass gathering tubular member 61, the eX- tremity 62 of which is preferably conical and fits into a rubber gasket 63, against which bears the coiled spring 64. To the gathering member 61 is secured by a pin 65, a stop collar 66 and the gathering member is formed with preferably two indentations 67 for the balls 68 which seat in perforations 69 in the end of spindle 43. to which is secured by a pin 70 a stop collar 71. Surrounding the end of spindle l43 is a sleeve 72 which is pressed against collar 7l by a spiral spring 73 which, at its other end, bears against a friction cone 74 feathered to spindle 43. The purpose of this arrangement is to permit the removal of the gathering member 61, which can be effected by pushing back sleeve 72 against the tension of spring 73 so as to allow the balls 68 to fall out of the perforations 69. The balls 68 clutch the gathering member to spindle 43.

It will be seen that the gathering device is so constructed and mounted that the gathering member 61 can oscillate in a vertical plane and also be revolved axially, while at the same time compressed air may be supplied thereto from the air pipe 58.

The mechanisms for giving the gathering device these movements and the operations which such movements accomphsh will now be described.

The supporting members 35, 35 are formed on their inner ends with machined ways 75, in which moves a slide 76 which is held in position by the overlapping strips 77, 77a. The cam roller 26, whlch has been described as moving in the cam way 25, turns on a )ivot 78 secured to the under side of 'slide l76. (in the upper side of slide. 76 is a pinion 79 turning on a pivot pin 80. The pinion 79 meshes on one side with a rack 81, formed on the strip 77, and on the other side with a rack 82 secured to a rod 83, square. in cross section, which slides on the slide 76 under strip 77 and at its other end in a guide 84 (Figs. 1 and 2) secured to the. bearing 36 on supporting member 35. This end of the rod 83 is formed on its under side with a rack 85 which meshes with a pinion 86 (Figs. 4 to 6 and Fig'. 19), keyed to shaft 40. By means of this mechanismI the movement of the cam roller in the cam-way 25 away from or toward the column 2O gives an oscillating movement in one direction or the other to the glass gathering and forming device. The. move-ment of the rod 83 has double, the amplitude of that of the cam. The first movement of the gathering and forming apparatus in thelv cycle, of its operations is the movement by which it is dipped in the glass pot. Supposing the parts to be in the position shown in'Fig. 1, their initial position relative to the cycle of operations of the machine, the movement of the cam follower outwardly in the cam-way causes the gathering member 61 to dip down into the body of glass 87 in the glass pot 88, which is opposite the revolving gathering mechanism at this period of its travel. As the cam follower 26 moves inwardly the gathering mechanism is moved out ot' the glass pot. 88. The dipping position ot' the gathering member 6l is shown in dotted lines in Fig. 1.

In order to gather the glass on the cud of the gatl'iering member 6l the latter is axially revolved while it is in the glass pot.. lhis is accomplished by the following mechanism: The. pinion 30, which has been described as meshing with the. circular rack 29, secured to the under side of the camcarrying ring 22, is fast on a shaft 89 turning in a bearing 9() on a bracket- 9l, bolted to the web 34 of the supportingl lframe, and carries the bevel gear 92 which meshes with a bevel gear 93 on a shaft 94 turning in a bearing 95 secured to the under side of the supporting member 35a (Figs. '7, 8 and 9), the shaft 94 being swivelled at 96 to a shaft 9T turning in a guide 98 (Figs. 2 and l0), on supporting member 35 and carrying a bevel gear 99 which meshes with a bevel gear 100 on a friction cone 101, which is keyed to shaft 42 and which frictionally e the cone 74described as having a. feate connection with the shaft 43. By this Jarrawement the gathering member 61 is frotated so long as the beveled gears 92, 93 are in mesh. The means for throwing these gears out of mesh/in order to stop the rotation vif-the gathering member 61 vwill be" horizontal position shown in Fig. 3, .180 removed from the initial'position of Fig 1. This is for the pur se ofmarvering the blank or the body `o glass gathered on1 the end of the gathering member 61.

f 8 and 9), by

wardly in the cam-way 25. During this The marver consists-of Amember 102 in the form of a V-shape trough provided with a plate 3 having a hub 104 (Figs.

eans of which the marvel' is pivotally moitnted on a bolt 105 secured tp the vertical we'b'of the supporting member The gathering device 1s turned to vthe position of ig. 3, with the blank (desig nated A in Fi 1 and A in Fig. 3) in contact with the fnarver by means of the rack and slide movement, above described, actuated by theretreat of the cam roller 26 1nmovement and while the blank is in the marver the rotation of the gathering member continues by the mechanism above described.

In order to give the blank the conical shape shown at A? in Fig. 4, the marrer, during the latter part of the time in which the blank is in contact with it, is tilted, as shown in Fio. 4. This tilting movement is accom lishei bv the following mechanism:`

0n a racket 1.06, bolted to the web 34 of the supporting frame, is pivoteda lever 107 carrying a cam roller 108 whlch, at the proper time, meets a cam 109 bolted to the lower ring 23 on the column 20. Lever 107 is connected by a link 110 with a bell crank 111 pivoted to a web k112 on the under side of bracket 106, the other arm of bell crank 111 being connected with the marver by a link 113. The marver is formed with a socket 114 for a spiral spring 115 which rests uponabracket 116 secured to the vertical Web of supporting member 35. In o rder to keep the lever and link mechanism 1n proper position when the roller 108 is free from cam V109, the bracket 106 is formed with a lug 117 for an adustable screw 118 which bears against the ever 107.

The blank having been brought, to the form showny at A in Fig. 4, the gathering device is turned out of the marver, first into the-dotted line position shown in Fig. 4, at which time air may be admitted through the gatherin device from an pipe 58, causing the blan to assume the hollow shape ably provided with the stop and lo 120, 121. The upper surface ofy pinion 30 illustrated. ai vA in Fig. 4. It will begun- .der'stood that any preferred mechanism may be vem loyed for controlling the delivery of the air to the gathering devicef As such mechanism forms in itself no part of my present invention, it is not shown nor described. From thedotted line position of Fig. 4 the gatherin device is turned tothe full line osition o v Fig. 5. The device is then oscil ated back and forth, for example, from the full line position ofvFig. 5 to the dotted line position, in order to elongate the blank to the configuration shown at A of this figure. The movement of the gathering device from the marvering position of Figs. 3 and 4 to the full line position of Fig. 5 and the oscillating movement indicated in Fig. 5 are accomplishedby means of the slide and rack mechanism actuated by the movements of theram roller 26 in` cam-way 25. l

WVhile the gathering device and blank are being swung back and forth, as shown in` Fig. 5, which, itmay be said, is preferably accompanied by a reduction of the air pres sure, the axial revolution of the gathering member 61 and the blank is stopped. This' is brought about by the following arrangement: The shaft 89 carrying gear 92 is mounted in its bearing so as to be capable of endwise movement therein, and a spiral spring 119 is interposed between bearing 90 and bevel gear 92, the shaft 89 being pg'efer.-

on the shaft is in the form of a frnstu'in of a cone, designated 122, which part, at the proper time, meets a cam 123 (Figs. 5 and 11), with the result that the gear 92 is shifted ont of mesh with gear 93. The axial revolution of. the gathering member thereupon ceases, to 'be resumed again when the pinion 30 passes out from under the other end of cam 123, which" is whenvthe oscillation of the gathering device ceases. r'

The next movement of the cam roller 26. in the cam-way brings the gathering device into the vertical position of Fig. 6, and the mits blank is thereupon enclosed in a mold` preferably, a paste mold, designated 124.' The means bv which the mold may-be made to -enclose the blank forms in itself no partl of my present invention, nor does the particular construction of the' mold. If desired, this step of the manufacture might be. car-I ried out by hand. At this juncture., air at considerable pressure is admitted to the blank through air pipe 58 so that the blank is gi\'cn the form shown at A in Fig. 6. At

the same time, the rotation ot' the gatheringr.I

lthe above deslription.

26 then returns the gatherinoc device, with the bulb thereon, to the initlal horizontal position of' the former, the mold` of course, having been removed. and the blank is removed from the gathering member 61 in any desired manner, and the gathering member is again dipped into the glass tank and again proceeds through the cycle of movements above described.

While the apparatus has been described as consisting in its operative parts of a single operating unit, it is obvious that it desirable, there might be a number of lil-:e units arrange-d to be operated by the same stationary cams and rack. As modifications in the form, construction, arrangement and in the particular iustrumentalities provided for carrying out my invention will readily suggest thi-mselvcs to those 'familiar with automatic machinery and with the glass art, I do not limit myself to the particulars shown and described except so -tar as the same are made limitations on certain of the claims herein.

The operation of the machine, as above described, will be readily understood from However. the Sequence of the operative manipulations of the parts Will be made clearer by reference yto Fig. 11, which shows the course of thc cam roller 26 in its cam-way 25. In this figure the cani roller is shown in the position which it takes between points (t. while causing the gathering device to move from its initial horizontal position to its gathering position in the glass pot 88 (Figs. 1 and 2); the movement outwardly of the cam roller giving an outward movement to slide 76 and, through pinion 79 a. multiplied movement in the same direction to rod S3 which, acting on the oscillating pinion 8G, turns 'the gathering device to the position described. The movement of cam roller 26 from the point b of the cam-way to the point c turns the gathering device from the dotted line position of Fig. 1 upwardly and over to the sition of Figs. 3 and 4. The interval Indicated by the points c, d on the cam, at which time the cam follower 26 has no movement, is the period in which lthe blank is in the marver. During the latter part of this period, roller 108 (Figs. 4 and 7) meets the marver cam 109 which` through the agency of the lever and link mechanismy 107, 110, 111, 113 rocks the marver to the position of Fig. 4. From Z to e the cam roller makes a sharp movement outwardly, which movement turns the gathering device to the full line position of Fig. 5, air being preferably admitted when the device is in the dotted line position of Fig. 4, the introduction of air continuing with the device in the full line position ofMFigh, while the cam roller is passing fromfp'oint e to f. The next movement of the cam, from f *c g, swings the gatherin device from the full line position to re dotted line position of Fig. 5; the movements of the cam to successive points f', g', f, g2 repeating these oscillating movements. The movement from g2 to h brings the device to the vertical position of Fig. 6, in which position the blank is enclosed in the mold, and the pressure of air which preferably has been decreased during the oscillating period is again increased so as to cause the blank to conform to the shape of the mold. From L to i the device is in the verticai position and the rotation of the same recommences after having been stopped by pinion 30 coming in Contact with cam 123' (Fig. 5), causing bevel gear 92 to be taken out of mesh with bevel gear 923v on the jointed shaft 94. 9T. which latter normally rotates spindle 43 ot' the gathering device and with it the gathering member 61, by means of beveled gears 99, 100, and friction cones 101, 74. B v its movement from to j the cam roller 2G returns the gathering device from its wrtieal position to its horizontal position, at which time, the device remains in substantially horizontal position while the roller moves from j to During this period the finished blank is removed.

I do not claim herein specifically the construction of the marver nor the combina-tion of the marver and gathering device, this mechanism being the subject matter and specifically claimed in my cepending application, Serial No. 594.049, filed November 25, 1910, which is a division ot the present application; the instrumentalities by which the marver operation is performed being claimed herein only in'eombination with other elements of the apparatus'.
